The frequency offset before the adjustment was approximately +2.81E-13 LTM to USNO and this was moved as close to zero as possible. The frequency drift compared to USNO before the adjustment was approximately +1.67E-15 and an adjustment was performed to take most of this out or at least flatten out the frequency drift.
